No doubt, it’s a scenario you have encountered — and successfully managed — on any number of occasions: A building owner wants restroom facilities or a commercial kitchen space where plumbing does not exist, or the nearest plumbing line is 10 or more feet away. So he or she asks you for an inspection, an assessment and a quote. The space happens to be on a second level, or in a basement, on a slab.
In any event, to create below-floor drainage with either conventional plumbing or sewage ejection, you immediately conclude that you must pound through concrete. That means a messy, noisy, time-consuming job — and a high cost. So high, in fact, that when your customer sees your estimate, chances are, they’ll tell you to forget it.
